recognized.The disk is connected to the data line but can be found from the disk location. We all know that two devices can be added to an online device, one master disk and one slave disk, and the jumper on the hard disk must also be configured as a master/slave device. Then, the corresponding settings are followed.The system still cannot find the primary disk. The analysis may be caused by a problem that occurs when the data line is connected to the primary disk. Change to a new data line. So

About IBM t60 system installation About IBM t60 system installationAbout System InstallationI have been using a recovery disk for t60 system recovery. However, there are too many built-in software. The key is that most of them are very junk.Therefore, it is especially necessary to install a fresh system.Because t60 uses a SATA hard disk without a soft drive, we cannot easily install the

The new ThinkPad e320 cannot be directly installed with XP, and the performance is slow when it is installed in compatibillity hard drive mode. There are two solutions, both of which have been verified and tried. Method 1: Use the nlite tool to merge the corresponding SATA hard drive into the installation disk and then copy it. Method 2: (Switch) ThinkPad E40 0578a59. After installing XP, you are ready to enable the ahci mode of the

Cinder supports a variety of backends in the backend, and it really fits the needs of the user. Recently, our company's own internal OpenStack platform with SATA, SSD glusterfs volume, studied the configuration of the next cinder multi backends. Actually, the main thing is cinder.conf.The cinder.conf configuration file is as follows:[default]enabled_backends = glusterfs1,glusterfs2 # enable two glusterfs volumedefault_volume_type = GLUSTERFS1 # Defaul

into the dead loop, constantly reminding, constantly reloading, all useless. So, each master of the road, rearrange the layout of the system, and constantly change the installation disk; The idea was right, but it didn't catch the key. Here are a few reasons: 1, most of them are installed Win7, especially 64-bit. 2, mostly with the new 2.5-inch 750g7200 turn of the hard drive. 3, the Machine BIOS option has SATA Operation (

standard PCI and FC interface for connecting the host or server, the application scope is relatively narrow. This is a high-performance memory, and the service life is very long, the drawback is the need to connect the independent power supply to protect data security, if the power loss will be lost data, so the DRAM type of solid-state hard disk for the server and other large equipment use, not suitable for individual users to use. Notebook solid state hard disk interface common types

How to install solid state hard disk installation tutorial The current mainstream solid-state hard disk interface for SATA and mSATA, where SATA is the most common, and msata is mainly applicable to notebooks, but now the new desktop computer motherboards are also beginning to support the mSATA interface, let's go over the details below.

If the primary hard drive fails, the system can start directly from the recovery drive and perform data recovery work. In addition, Intel will support SATA Port multiplier technology in the ICH9 South Bridge. According to the motherboard manufacturer, most of the Sou

Full introduction to installing the operating system for IBM t60/X60) 1. BIOS settings. This step is for t60/X60. Press F1 to enter bios, enter configuration, and then set the SATA mode to compatibility (compatible mode) in Sata. The default mode is ahci (Advanced Control Interface ), this step is very important; otherwise, the operating system will be installed with a blue screen, the reason is that the

Nowadays, hard disks are basically serial ports (SATA). Compared with parallel hard drives (IDES), serial hard disks have many advantages. However, the hard drive of most computers is still working in IDE mode. This is because the operating systems before xp sp3 do not contain SATA drivers. Therefore, to install XP of SP2, You must select the IDE mode for the serial hard drive; otherwise, a blue screen is d

card. 2. device connection 　　IDE device connection: Ide devices include optical drives and hard disks. Generally, ide1 and ide2 are marked on the motherboard (Figure 7). Two groups of IDE devices can be connected through the motherboard. Normally, we connect the hard disk to ide1 and the optical drive to ied2. Two types of connections are required for normal operation of this type of equipment: one is an 80-pin data cable (40-pin optical drive) and the other is a 4-core power cord. During conn

[Host planning and disk partitioning] disk partitioning MBR Relationship between the disk connection method and the device file nameThe mainstream disk interface is the SATA interface.Disk interfaces such as SATA, USB, and SCSI are all driven by the SCSI module. Therefore, the disk device file names of these interfaces are in the/dev/sd [a-p] format. The order depends on the order in which the Linux kernel

file types. If you want to restore a PDF file, the recovery software will find the hexadecimal magic number "25504446", which is exactly the "% PDF" in ASCII code ". The recovery software searches for all magic numbers and then you can choose which deleted file to recover. If a part of a file is overwritten, the entire file will be damaged. This file can be recovered normally, but the content may be useless. For example, restoring a damaged JPEG file will be meaningless, because the image Viewe
